May 04, 2020 · Atomic properties of sulfur. The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find sulfur within the periodic table of the elements, sulfur is in group 16 and period 3. Sulfur has an atomic mass of 32,065 u.
Calculate the air-fuel ratio on a mass basis. Solution: One approach to this problem is to write the combustion equation for each of the combustible elements per 100 kg of fuel. The molar composition per 100 kg of fuel is found first. Kmol S / 100 kg fuel = 0.6/32 = 0.02. Kmol H 2 / 100 kg fuel = 5.7/2 = 2.85. Kmol C / 100 kg fuel=79.2/12=6.60

The mass of 1 mole of anything can be determined from its molecular formula. In the case of SO2 it would be 64g/mol. The volume of any gas at STP is 22.4L/mol. To determine the density, you divide the mass by the volume (64g/mol / 22.4L/mol).
